SIPHON-PUMP.

Specification of Letters Patent.

Application filed December 18,1908.

Patented April 20, 1809;

Serial No. 4268,214;

To all who m it may concern:

Be it known that I, WILLIAM LLOYD RICHARDS, a citizen of the United States, residing at lfilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented new and useful Improvements in Siphon-Pumps, of which the following is a specification ,7

This invention is an improved siphon pump especially adapted for use in se arating cream from milk in milk bottles for lnfant feeding, but also adapted for use for decanting lime water, hroths, for removing water from gold sh bowls pre aratory to replacing the fresh water and a so for use in pharmaceutical and chemical works.

The object of my invention isto provide an inniroved siphon which may he started without the necessity of creating a suction with the mouth, a further object being to ctl'cct such improvements in the construction of the siphon as to enable the same to be readily cleansed, a further object being to cilcct such improvements in the construction of the siphon as to enable the same to be readily p aced in and adapted for operation in connection with a vessel such as an ordinary milk bottle or the like.

The accompanying drawing is partly an elevation and partly a sectional View of a siphon pump constructed in accordance with my invention showing the use in separating the milk from the cream in an ordinary milk bottle.

in accordance with my invention the siphon 1, which in practice is preferably made of glass, but which may bemade of any other suitable material, has its longer arm 2 disposed at an angle to its shorter arm 3. in practice, the longer arm is usually slightly more than twice the length. of the shorter arm, but this may be varied within the scope of my invention and I do not desire to limit myself in this particular. The longer arm is connected Lo the shorter arm, in the angle between them, by the neck or connecting portion 4 which is substantially send-circular and the least diameter of which about corresponds with the thickness ol' one side of the 1 nouth' u of a vessel 1), such as an ordinar milk-bottle or the like, so that the said hen connecting col-tron or llOlfilQ- of the siphon is adapted to ht on one side ol the mouth of the vessel so as to support the siphon with its of the shorter arm, and with its lon er arm extending downwardly and outward y from one side of the vessel and terminating at a point below the plane of the lower end of the shorter arm. q I

In practice where the siphonis designed for special use and in connection with a particular type of vessels, as for instance where the si )hon is for use in connection with a milk ottle for'separating the cream from the milk by drawing off the cream from above the milk, the shorter arm of the siphon is of a determinate length with reference to the depth of the cream asillustrated in the drawing, that is to say, said shorter arm is of such length as to extend to within a suliicient distance from the top of the vessel to cause all or practically all of the cream to be drawn from the vessel above the milk and leave the milk remaining in the vessel after the cream has been thus drawn. 7 v

In order to start the siphon in operation, I provide the same with a plunger 5 for 0 eration in the longer arm of the si hon. his plunger is extremely flexible an in practice 18 made of some extremely flexible material such as rubber to adapt the plunger to bend and conform to the shape of the neck portion of the siphon and the said plunger is also elastic so as to cause it to fit snugly in the,

bore of the siphon. The plunger is operated by a rod 6 to the inner end of which it is attached, the-said rod being rigid and in practice'being made of suitable wire.

Before using the si hon, the plunger is pushed upwardly in the longer arm. The siphon having been then a )propriately placed in the vessel, as shown in t 1e drawin so that the shorter arm thereof becomes su merged to the required extent, the lunger is drawn out of the end and from the onger arm of the siphon so as to exhaust the air therefrom and start a lion of the liquid or contents of the vessel through the siphon and from the longer arm thereol, as will be readily understood. 'lhc plunger is not only useful in starting the siphon in operation, but is also useful as a stopper to cut oil the flow of liquid from the siphon when desired and owing to the Horrible nature of the plunger, the plunger is also extremely useful for cleansing or assisti in the aiaansing 0f the si ham, as it thereof and a n'gid operating rod for said may a drama from. and no and t ersoli rglungmu 16 That is claimad. is:- In tastimflny whereof K affix my signature A si hon having its longer arm at an angle in presence of two Witnesses. 5 to its 510m: arm and provided with a curved WILLIAM LLQYD REPHARDS.
